The value of the social-networking site Facebook shares has crossed 100 billion dollars in a pre-IPO rally.

Some 150,000 Facebook shares sold for 44 dollars a piece in the latest auction on SharesPost, a trading platform for stock in private companies. That’s a 10 percent jump from last week, when 100,000 shares went for 40 dollars each.

At 44 dollar a share, Facebook would be worth about 103.5 billion dollars, The New York Post reports.

Before the company filed to go public last week, its shares were selling in the low 30 dollars for much of last year on private exchanges like SharesPost and SecondMarket.

The private market has heated up as shareholders look to sell some stock ahead of an enforced lockup period, while buyers are banking that the shares will pop when Facebook goes public, expected in about May.
